I was coming home down the M4 from London and decided to stop at a restaurant a mile off the motorway. Manouvering in the pub car park I felt the forward 1st gear and reverse a bit sharp and the electric fan had come on. Parked up and had meal. On leaving the car park the car would not change up from 1st gear. The engine management light came on the dash. So went back to the car park and called roadside assistance. They got us loaded up on a transporter and brought home......embarrasing...!... Local MB dealer says its the intelligent servo module that needs replacing and will cost £1400 to sort. There was no warning here apart from the sharpness on engaging gears in the pub car park as described. The car has only done 36K miles but is 7 years old and I wonder if you can tell me as to how common this problem is and should I be looking out for anything else that may happen as a result or will I be back to motoring normality?
